REGULATING DEVICE FOR MOlSTEN-ING LEAVES 0F PRESS-COPY BOOKS.

SPECIFICATION forming part ofv Letters Patent No. 516,953, dated tfarch 20, 1894. Application filed November 19, 1892.V Serial No. 452,557; (No model.) v

T0 all whom it may concer-n: j

Be it known that I, OWEN K. TRUITT, a citizen of the United States, residing at Washington, in the Districtof Columbia, have invented a certain new, useful, and valuable Improvement in Water-Regulators Used in Connection with Devices for Moistening .of the Wick, can be perfectly andconveniently regulated.

I will proceed to explain my invention more fully in connection with the annexed drawings, in which- Figure 1 is a front View of a moistening device with my improvement added thereto. Fig. 2 is a side View of the same.

Before proceeding further to describe my invention I would explain that a great objection to devices for nioistening the leaves of letter press-books has been that on account of a vacuum forming at thetop of the reservoir, upon expanding a part of the Watery in using the brush, this vacuum prevents a further flow of the water into the wick, and prevents it from sufficiently moistening the leaves, and this serions objection occurs especially when the brush is used for anyv considerable time continuously. It will be seen that my invention obviates this great objection.`

, Within the reservoir A I arrange a pneumatic tube B, the end B projecting slightly beyond the edge of the reservoir and said end having an opening Ba therein. The inner end B4 of the tube is carried to the top of the reservoir for the purpose to be hereinafter explained.

The lever C, pivoted at O', as shown, is provided With a piece of rubber C2 which is'normally kept pressed against the opening Ba by f the action of the spring C3 and eiectually closes said opening, but a slight pressure upon the end C4 of the lever causes the rubber C2 to recede from the opening. The purpose of the valve thus formed is to admit air, at will, into thev tube B which conducts it to the top of the reservoir and breaks any partly formed vacuum created when thewick D is held downward or when the device is in actual use,

said wick being-securely held between thev the reservoir and provided with an orifice,

and mechanism for opening or closing said orifice.

2. In a moistening device of the character described, the combination, with a reservoir having one of its ends open and a `wick Within the'reservoir projecting .through the open end, of a tube within the reservoir having one `end terminating over the wick and the other end projecting below the reservoir and provided with an orifice, and a spring pressed lever pivoted to the reservoir and carrying a plug or the like for -closing the sald orifice.

In testimony whereof I afx mysignature inv l presence of two witnesses.
